Getting error attempting to update custom field value from Regex result using Scriptrunner

Paul J. Hecker

New to Scriptrunner.  Developing script to update custom field value from last issue comment using RegEx.  The target string format in the comment is "Ticket#123456". Getting error result when testing in Scriptrunner console

class com.riadalabs.jira.plugins.insight.common.exception.GroovyInsightException

GroovyInsightException: No such property: event for class: Script1'

Would appreciate any information on the nature of the error.

Thanks!

Figured it out with some help.  Added logging (now removed) and better string manipulation and ran the script as a Listener rather than from the Scriptrunner console.  Interestingly, even though the listener works, it still errors in the console.  Script shown below with resources used to build it.
